Ureaplasma urealyticum (UU) is closely related to human diseases including non-gonococcal urethritis (NGU), infertility, premature membranes and neonatal bronchopulmonary dysplasia. Researches on the pathogenicity of UU have become a hot topic in recent years, and suggest that many potential pathogenicity genes or putative pathogenicity islands are involved in its virulence. Moreover, the biovar and serum types of UU, the infection concentration and the state of the host immune system are also important to determine whether UU can cause human disease or not. In this article the recent progress of researches in the pathogenicity of UU is reviewed.

A group of 180 men who visited Urology Department of Severance hospital, including 115 patients with nongonococcal urethritis (N.G.U.), 27 patients with prostatitis, 13 patients with gonococcal urethritis (G.U.) and 25 healthy medical student controls were investigated for the isolation of Ureaplasma urealyticum (T-strain mycoplasma) from the specimen of urethral discharge, urine and semen. Taylor-Pobinson media of T-broth and T-agar was used for the isolation of Ureaplasma urealyticum. To the best of our knowledge, the study on the culture of Ureaplasma urealyticum was reported for the first time in Korea. The following results were obtained: 1. The isolation rate of Ureaplasma urealyticum in nongonococcal urethritis (53.0%) revealed highest of those in the other three groups of prostatitis, gonococcal urethritis and control (40.7%, 38.4% and 16.0% respectively). 2. As for the specimens, urethral discharge revealed higher isolation rate of Ureaplasma urealyticum (54.6%)than first voided urine (50.0%). 3. The more consorts patients had, the higher positive culture rate of Ureaplasma urealyticum were revealed. The isolation rate in case of more than one causal in nongonococcal urethritis (71.1%) revealed much higher than in case of marital only (42.8%), one regular (41.1%) and one causal (41.0%). 4. 18.7% of isolation rate of Ureaplasma urealyticum revealed in patients with nongonococcal urethritis who visited the clinic in later than 4 weeks after the symptoms developed. However, the isolation rate in patients who visited within 4 weeks revealed 58.9%. The lower isolation rate of Ureaplasma in the late treatment seekers might be probably due to the suppression effect against Ureaplasma urealyticum from the possible previous self antibiotic treatment. 5. Attachment of Ureaplasma urealyticum mostly to the neck and head portion of the spermatozoa seemed to play a role to affect the motility of sperms.

PURPOSE: We wanted to investigate the usefulness of Mycofast (MYCOFAST(R) Evolution 2, International Microbio, France) for Ureaplasma urealyticum (U. urealyticum) and Mycoplasma hominis (M. hominis) in association with nongonococcal genitourinary infections. MATERIALS AND METHODS: 530 patients visited our department for genitourinary infection symptoms or for the evaluation of sexually transmitted disease. The genital swabs were first vortexed in Mycofast transport broth. A volume of 100mul of liquid sample was innoculated to each well of the Mycofast broths and 0.5mul of liquid sample was innoculated to A7 agar culture media (International Microbio, France). The Mycofast broths were incubated at 35-37 degrees C for 36 hrs, and the A7 agar culture media was incubated for 4 days. We compaired Mycofast with A7 agar culture for the sensitivity, specificity, the positive and negative predictive values and the antibiotic susceptable profiles. RESULTS: Of the 530 samples submitted, 165 samples were positive by the A7 agar culture and 162 samples were positive by Mycofast. 157 samples were positive by both methods. Of the 365 samples that were negative by the A7 agar culture, 360 samples were also negative by the Mycofast. In this study, Mycofast had a sensitivity and specificity of 95% and 98%, respectively, and a positive and negative predictive value of 96% and 97%, respectively. The Mycofast drug susceptibility tests indicate a high susceptibility to doxycyclin as follows: U. urealyticum: 86.3%; M. hominis: 85.0% and both organisms with simultaneous isolation: 75.8%. CONCLUSIONS: Mycofast was an easy test to perform and it proved to be a practical and reliable method for isolating the Mycoplasma and Ureaplasma species for making the diagnosis of nongonococcal genitourinary infections, and it showed the added benefit of determining the limited susceptibilities of the isolated strains.

We have experienced the female urethral syndrome in many patient, but we are embarrassed in identifying the exact cause of each case and searching for the treatment modalities. I thought there was a possibility of infection or local irritation by Ureaplasma urealyticum and Chlamydia trachomatis as an evoking factor of this syndrome. We have reviewed 32 women referred to Severance Hospital who complained irritative symptom of lower urinary tract without evidence of UTI and have come to the conclusion as follows 1. There was high isolation rate of ureaplasma urealyticum and Chlamydia trachomatis in female urethral syndrome. 2. There was no difference between isolation rate and age, or menopause. 3. There was high correlation between urethral and cervical isolation.
